My invention, relates "to doubleor multiplebarre'led shot guns. Its object is to provide -an improved trigger mechanism wherein successive pulls on the same'trigger serve 'tofire the=barrels 5 successively. More especially the invention provides an arrangement to this end whichisiapplicable to standard or conventional gun designs without substantial change or re-arrangement-of the existing elements thereof and "is 'ex- 10. treme'ly simple so .as to add "but little to the cost thereof, thereby permitting guns originally designed for multiple-trigger action in the usual way .to be adapted readily to single-trigger action.

Speaking generally, my invention consists in using as the operating connection between 'the single tri er (or the tr gger which fires the first barrel) and that portion of. the firing mechanism which serves "the barrel to "be ffired second, 29 a main member located at one side of the firing mechanisms for both'barrels which member has .a) projection or projections thereon or otherwise associated therewith, extending substantially transversely of the gun, and forming the inter- ,25 connection to produce the desired functioning. Such placement of the main member permits it to be or plate rorm and disposes the major part of the mechanism which is to be added to the 'standar.d design mainly atone side of, or outside or, the space occupied by fi n pins,

mers/hammer springs, and .searsfif any, where space can easily 'be .made for it, while the inter- ..connedting ,proiections oro'ther transverse mem- 'bers thereon will "in most cases findflroom -for ,operationintnont .or rear or under or over :the exi t ng parts of .the firing mechanism .without ,intm'ierlng with the proper "functions of the latter. The invention is exemplified in two embodia .ments in the accomp n drawings, in which:

Fig. '7 is a ventical section about on line VII-VII of Fig. 2. Fig.1 5 is a perspective view illustrating another form of my invention as applied to a doublebarreled shot gun, 'both hammers 'being shown cocked. Fig.9 illustrates the parts immediately after "the first barrel has been fired. is similar to '9 excepting that the parts are in positions they occupy after the trigger has been released. Fig. 11 illustratesthe positions of the same parts immediately after the second barrel has been fired.

1 to 7 illustrate the invention applied to a standard form of doubledbarreled "shot guns having a "well known 'form-of firing mechanism. The receiver or frame oi the gun will be recognized at I and the barrels at 2, the latter being hinged 'to' the frame-at "3; also-the top lever d -fer :locking the gun closed, and the sliding safety thumb piece at 5. Tln'sparticular form of safety functions by the action of the sliding thumb piece :5 swinging the nose 6 of the safety lever'l over and away from "the rear ends of the triggers 8 and?! in a customary mannerandas will be recoglfized from the drawings; any other type of. safety might be used. Also as customary the reciprocating rod 10, connected to the lever 1, A39 serves to push the-safety to the safe position when the gun :is broken.

The two triggers '8 andB-are fulcrumed on the 'frameby.a pivot pin [3; only one trigger *8 need ibe'provided with the customary ringer or pull piece f2 since the use of one'trigger isto fire both barrels. Sears 14 and f5, hinged to the frame'at "16, form the control 'cormection between the two triggers 8 and 9 respectively and the two 11ammers .or spring-pressed firing pins 11 and 18 respectively (herein called hammers) so that the .upward movement of either trigger lifts =its sear "and'fires 'the corresponding barrel; the spring 19 depresses both scars and through them presses the triggers toward their normal positions, in which they abut against the cross pin 20, all as .customary.

The triggerB having the finger piece or pull 12 formed on it is arranged in permanent cooperating relationto the sear "l4 and its hammer 11 i. e., the pull on this trigger always releases the (righthand) hammer if it is cocked, although this action is not indispensible. By the effect of a plate member 24 this same trigger -8 may also release the 'l'efthandhannner after the righthand 55 frame by screw 3|, acts to press the plate 24 forwardly; conveniently a pin or screw 32 is provided in the rear portion of the plate forthe plate-end of the spring to rest against as shown in Fig. 1. The plate 2 5 is thus'arranged for forward and backward movement, and it may also turn or rock on its pin H3 in a 'yertical plane. 7, A cross-pin 25 carried rigidly by the plate 24 m extending transversely thereof is arranged to enter the notches 26and 2? provided in the ends of the two triggers 8 and 9 when the plate 24, is allowed to :move to its forward position (Fig. 4) and the triggers are in their normal positions, thus lock-E ing'the two triggers together, but, while the plate 261 occupies its rearward position this cross pin 25;;is entirely free of the trigger notches 26 and 2'! (Fig; 1). The plate 26 also has andother transverse projection 35 and which may be simply a bent-over tab on. the body of the plate. This member lies in the path of the hammer ll of the first barrel to befired. V

The operation-of the mechanism is evident. from the foregoing. The breaking of the gunfserves to cock both hammers (by usual mechanism, not shown) and they cocking of hammer l'l engages .the tab 3 0 and thereby pushes the plate'24 rear.- ward against the'thrust of springl and the cross pin 25 is thus held clear of the notches 26 and 21:as long as hammer 1] remains cocked (Fig. 1). A'pull on the trigger 8- will n'o w'fir'e the righthand barrel. The spring 29 tends to thrust the plate 24 forward immediately the hammer l1 falls, but its pin 25 now abuts. against the shoulder 35 of the trigger which prevents such movement for the moment (Fig. 2). On releasing the-pull on the trigger 8'the cross pin 25 enters the two trigger notches 2 6 and 2? thus locking them to- .gether (Fig. 4) 7 A pull on the trigger 8 wil1 now liftthe cross pin, 25 with it (the plate 24 turning on its pin l3 and within its slot 24 and this lifts both triggers including'trigger 9, and there.- by fires the secondbarrel (Fig. 5).

.It will be apparent that the forms of the plate 24, the transverse members 25 and 30, the relation of theseand corresponding parts to each other and to the firing mechanism, the form, of the firing mechanism, and the mechanism whereby the plate 24 is caused to move forward and'back, are all subject to variation. Also, it is not essential thattrigg'ers be locked together for the firing of ;the second barrel; other parts may be engaged to bring about firing of the second barrel. As an example of the latter, Figs. 8, 9, 10 and 11 illustrate an arrangement wherein a transverse member corresponding to pin 25 coacts with the sears instead of the triggers. The gun of these figures is substantially'the same as that of Fig. 1. The same framel, top lever 4, safety thumb piece 5, and spring-pressed hammers or firing pins l1 and I8, and sear spring l9 will be recognized.

.The two sears are pivoted to the frame at, 40

substantially. as before. The scar 4i permanently relates the trigger 42 to the first hammer ll to fall; The sear, 53 cooperates with the second hammer I8. The vertical plate 44 at the side of the firing mechanism, its transverse member 45, spring 49, and second transverse portion 50 for cooperation with ll, are substantially like the corresponding parts 24, 25, 29 and. 30 of the preceding figures. In the present instance however, the transverse member or cross pin 45 is relocated, being placed immediately below the lower edges of the two'se'ars 4 I- and 43, and the sear ll of the first (righthand) barrel to be firedis' provided with a notch 5] outside of which the cross pin l5 stands when the plate M is in its rearward position and which the pin 55 enters as the plate moves forward. Below the notch 5!, a shoulder 52'serves the same purpose as the shoulder 35 of thepreceding figures (Fig. 9). When the gun is cooked initially the plate 44 is thrust to and held in its'rearward position as before (Fig. 8).

A pull on the trigger 42 now lifts only the sear 4|, firing the righthand barrel and freeing the plate 44 at the transverse member .50; the shoulder 52 prevents forward movement of the plate forithe moment however (Fig- 9). When the trigger is completely released the plate 64 moves forward and the cross pin enters the sear notch 5| (Fig. 10). Asecond pull on-the'trigger not only raises sear 4| again, however, but also this sear now raises the cross pin' 45 (tipping plate M on its mounting pin J3 asbefore), andthe pin raises the sear 43, thus firing the second barrel (Fig. 11). A subsequent release of the trigger'r'estores the parts to their starting positions.

In. general, it will be apparent that my invenvion is not limited to the details of construction and operation described above except as appears hereinafter in the claims.
